I continually do searches on the same flight numbers and/or the same airport ID’s.
Re-entering the flight number or airport name gets old after a while.
Have you considered programming “drop down” boxes for each of the Live Flight Tracker entry fields to display the last 4-5 entries? The user could then click on the relevant entry and not have to enter the text again.
BTW, FlightAware is great…I can’t express how grateful I am for access to the product.
